Why should I have SiS Whey Protein?

SiS Whey Protein is a great tasting, convenient way to increase daily protein intake. It is recommended that 1.4-1.6 grams of protein per kg of body weight is consumed each day in order to promote lean muscle mass. For a 75kg male who trains regularly that would equate to 120g of protein per day.

FAQ's

SiS Whey Protein can be used with or between meals to support lean muscle mass or immediately after strength and conditioning sessions, with the goal of ingesting 20-25g of protein every 3-4 hours.

Do I mix with water or milk?

Although milk is high in protein, it's also high in carbohydrate and is made up of 80% casein, which is slow digesting. Mix with water to increase absorption rates, which is ideal for use post exercise.
